Study of 230/11 kV Substation Under Different Type of Faults

Abstract

In this paper a substation model is represented with current technologies which gives a new look to the idea of a substations. A transitory comparison of a voltage with respect to time distribution is shown for the presence of components in a 230/11 kV substation with application of single-line-to-ground fault, double-line-to-ground fault and an external surge with the effect of lightning included as a whole affecting all the components. Positive sequence resistance and zero sequence resistances are varied accordingly for change in condition of the parameters and equipment. Simulation of a 230/11 kV substation model is shown by different circumstances with the help of ATP/EMTP is shown in this paper.
